To all 'whom it may concer/n:

Be it known that I, WILLIAM L. DEMING', a citizen of the United Statesof America, residing at Salem, in the county of Columbiana and lState ofOhio, have invented a certain new.'l and useful Improvement in Faucets,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings.y

This invention relates to faucets and is particularly concerned with theprovision of a combined faucet and mixer which is well' adapted for usein connection with existing types of shower bath apparatus.

Various mixers and valve control mechanisms have beenemployed in bathingapparatus for controlling the temperature of the Water, and for causingan intermixture between the hot and cold currents intermediate the inletvalve and the discharge point.

In most of these cases, however, there is no provision for controllingthe flow of water so vfar as quantity is concerned, other than byoperation of the valves which are connected with the control handle. Insuch cases, if the cold water is turned on at another point in the line,the supply of cold water at the shower is thereby decreased whereuponthe bather is exposed to a sudden` flow of hot water. Again, in numerousinstances the control valves are so arranged that the hot water may besuddenly turned on by the operator himself as the handlel is bei-ngmoved from the olf to the activel position.

One of the objects of my invention, therefore, is the provision of acombined faucet and mixer which will insure mixing betweenlthe hot andcold fluids, and

40 at the same time prevent a sudden excess of hot water as the coldwater is tapped at another point in the line. Another object is theprovision of a control mechanism for regulating the temperature of thebathing fluid by manipulatingl a single handle, to-

gether with the provision of means for preventing the operator fromAturning on the hot water unexpectedly. p 1 N In carrying out myinvention, I employ a pairof hot and coldl water cocks each having arotatable plug, and I provide a connecting link which extends betweenthe plugs in lsuch mannelifthat -movement of one causessimultaneo1s`iovement of the other, and-I provide channels ywithin theplugs,

a thorough lwhich channels are s o positioned in relation to each otherthat the' fluid is caused to low at varying degrees from cold to hot,asthe control handle is moved from either extreme to the `middle position.After the water passesdshrough the respective valves, it flows throughmy mixing device, which 'thoroughly mixes the hot and cold water, and atthe same Itime prevents an excessive .flow of hot water should the *coldwater be tapped at another point in the line.

The means for accomplishing the above objects will be more fully setforth in the following, description which relates to the drawings, andthe essential' characteristics of my invention will be set forth in theclaims.

In the drawings, Fig. 1 is an elevation of av shower device havingcontrol mechanism embodying features of my invention; Fig. 2 is anenlarged elevation partly 'in section,

showing the valve control mechanism and cocks.-

My valve mechanism is adapted for use eitherwith or without the mixingdevice shown. The'valve control mechanism functions to mix the hot andcold water when a basin or receptacle is positioned directly beneath thefaucet, while the mixing device functions to thoroughly intermix thefluids when, a shower nozzle is employed as in Fig. 1. Y I have shown mydevice in connection with a shower bath wherein 10 represents a housinghaving hot and 'cold water pipes therein, which lead to a faucetindicated generally at 1 1, and thence through a mixing device v12, aflexible tube 13 and a discharge nozzle 14. A bathing apparatusembodying features shown in Fig.` 1 is illustrated and described in mycopending application, Serial No.v 319,718, filed August 25, 1919, andreference may be had thereto' for claims covering the subject matter ofthe bathing apparatus in general. This application is a division of theabot'e CO-pending application.

rlfhe faucet. control mechanism as indicated in Fig. 2 is preferablycontained within al housing 20, and comprises hot and cold waterconduits as at 21 and 22, there being a revolving plug cock 23 and 24 ineach respectively. The respective plugs arek preferably constructed withlaterally bent stems designated 25 and 26, which stems are connected bya link 27 and pivoted to each end thereof as at 28 and 29, and operableby a common handle 30 constituting an extension of one of the stems, forexample 25.

From one of these cocks, preferably the cold water cock 24, I provide.as shown in Fig. 5 a downwardly curving discharge passageway 31, andinto this passageway 1 provide a discharge conduit 32 leading from theother cock. The two conduits 31 and 32, where they are concentric,effect an ejector action whereby a dischargejfrom the conduit 32 tendsto draw liquid through the conduit 31. The result is that if thepressure is reduced only in the cold water conduit 31, other conditionsremaining constant, then the flow through the'hot water conduit tends toaccelerate the discharge through the reduced pressure passageway, andthus to preserve a uniform temperature of the mixture. This is ofparticular value in preventing the discharged water from becomingsuddenly too hot, which might ordinarily result from the cold waterconduit being tapped at some other point before reaching the faucet. 1nsuch instances, the ejector action of the hot water tends to retain theproper supply of cold water.

ril`he hot and cold water cocks are so arranged that when the handle 30is in either extreme position, both cocks will bein closed or offposition. Movement of the handle toward the mid position, which may bein either direction depending upon which closed position it is in. willsuccessively open the cold water cock only, then both hot and cold` iproducing warm water and finally the hot only. The handle may becontinued in movement in the same direction to the other extremeposition, during which operation the reverse sequence will occur, givingin succession, warm water and cold water, before reaching the closed oroff7 position. The successive positions of the ground lkeys or plugsconstituting the seven stages from one extreme position, of the handleto the other are namely: closed, cold, warm, hot, warm, cold, closed.

As will be apparent from Figs. 6 to 12, the cold water cock is providedwith twoway channels 40 and 41, while the hot water cock has a singlechannel 42 with enlarged offset ends 43 and 44, whereby the desired flowof water may be obtained by movement of the handle in either direction.in indicator may be employed with the faucet in any desired manner andaccordingly, l have Lasagne shown a pointer 45 on the link I27, whichpointer is movable over the scale 46 and is graduated in accordance withthe various positions of the hot and cold water cocks. This scale may bepositioned on the front of the casing 20.

The device described and as illustrated in Fig. 5 may be employed wherea basin or receptacle is positioned directly 4beneath the faucet forreceiving the discharged fluid. To effectively mix the hot and coldwater, however, whena shower nozzle is attached to the dischargepassageway 31, ll provide a device, shown generally at 12 in Fig. 1 andin detail in Figs-2, 3 and 4, which device is positioned between thefaucet and the' flexible tube 13. As shown, this device comprises aU-shaped pipe removably connected at one end of the discharge end of thefaucet casing 20 and at the other end to the tube 13. The lower portionof the U-shaped conduit is extended upwardly into an internal ridge orpeak 50 which divides the conduit into two passageways extendinglongitudinally therethrough. At the discharge end of the U-shapedconduit, il provide a bams in the form of a disk-like plate 51 havingorifices therethrough, preferably a. central straight orifice 52, and aplurality of inclined orifices 53 near the edge thereof. Adjacent thisdisk, the conduit 12 may bev provided with a screwthreaded portion 54onto which extends a flanged coupling 55 connected with the flexibleconduit 13.

rlhe result of the above described construction is,.that the waterdischarged from the faucetfirst strikes the ridge 50 which tends tosplit the stream and give it a lateral motion which partially mixes it.Then, as the stream reaches the bafiie 51, part of 1t' passes directlythrough the central orifice 52 and part is directed by the obliqueorifices 53 toward the orifice 52, whereby ay thorough mixture ofthe'hotI and cold water is effected before itenters the tube 13.

Any suitable means may be employed for detachably connecting theU-shaped conduit 12 with the casing 20, but I have shown for thispurpose, a bail hinged to the U- shaped pipe and adapted to extend overa lug 61 on the faucet casing. A suitable thumb screw 62, passingthrough the bail, is adapted to bear against the lug for holding thedevice in position, leakage being prevented by a gasket 63 between thetol-shaped pipe and the lower portion of the discharge conduit 31. Acentering lug or pipe 65 maybe employed for retainingl the conduit 12 inadjusted relation with the discharge conduit 31. Centrally located onthe link 2'? and adjacent the casing, I provide a lug 64 which isarranged to be employed for limiting the movement of the link wheneverthe shower conduit is in use. Such limitation is effected by reason ofthe fact that the lng is central position of the handle so as to cause4a discharge of hot water, without permitting some cold water to flowthrough the condult 31. When using the shower, this safety de-v vice isoperated regardless of the 0E posi'- tion in which the handle 30 mayhave been left prior to thel attachmentof the shower conduit. When thebail 60, having the thumb screw 62 is removed, the mixer is no longerrequired, and since ythere is then no cooperation between the set screw62 and lug 64, the handle 30 may be moved through all of the sta es,from onel extreme to the other'. Accor ingly, the handle may be so movedthat hot water only, if desired, may be permitted to ow into the basin,or receptacle, positioned. directly beneath the discharge conduit I31.By loosening the set screw the bailmay be readily swung aside and theU-shaped pipe disconnected, whereupon the bail furnishes convenientmeans for hanging the disconnected pipe and tubing on a suitablesupport. Y This disconnection is effected r,without necessitating anydisturbance of the connectionbetween the U-shaped member and theflexible conduit.

From the foregoing description it will be seen" that l have provided acombined faucet and mixer, which is Well adapted for use in connectionwith a bathing apparatus, either with' or `withoutv a shower attachment,and that l have provided a mixer which,

when used with hot and cold water, is soI arranged that a current havingone temerature will induce the How of current having anothertemperature.' Accordingly, `it will be seen that a device embodying myinvention prevents a sudden .flow of hot water if the cold water istapped at another point in the line. A further feature, as will benoticed, from the description, is that the temperature may be variedfrom cold to hot .by moving the control vhandle fromv either extreme tothe middle point in its course of travel, and that a satisfactory safetydevice is provided when the tube 12 is used for preventing the suddenflow of hot water, by inadvertently moving the handle to the mid pointof its-course of travel. .Having thus described my invention, l claim:
